vhad to the accompanying drawings, which form a part of this specification. v My invent-ion relates to permutation locks shown in the accompanying 'drawings and i if moreparticularl'yf described in the follow-v ng specification and claims. A The cobject of my invention is to provide a simple and inexpensive lock of thecharacter described which may be employed as U a steering wheel lock lforI automobiles, a

tire lock, door lock'or the like.

One of the objects ofthe invention is to provide a device having relatively few parts,

simple in its construction `and operation and which will not readily get out oiiorder.

' lVi'th the foregoing and other objects -inI view which will appear as the description proceeds, the invention further resides in the combination and'arrangement 'ofl parts and in the details of constructionhereinafter described and claimed, it beingunderst'ood that changes may be made in the 'precise embodiment of' the invention herein vvdisclosed without. departingfrom the spirit of 235 the same.v i

Referring now tothe letters of reference placed upon the'drawings: Y

A., denotes the lock casing rovided rwithl i adapted to B upon the edge of' a lrotatable lcap B overlappin'g'the wall of the'ca'sing. C, isa centrally disposed bolt rigidly securedatone end to the cap B, provided kwith a projecting tongue C which iisl adapted yto lrotate in a. stepped-counterbore ,A2 ,formed inthe casing. D, denotes aiXed sleeve'ortum- 'bler slotted as at D "to receive the tongue C of the bolt" when 'brought into proper j registration therewith. The sleeve or tumbler D is cmuiterbcredl at its upper-end as indicated at D2 and is provided-with a vertical slot D3 in the counterbored end. E, is atumbler sleeved in the bore oit' the fixed sleeve or tumbler D having an enlarged head E projecting into the counterbored portion of the latter. The enlarged head E is also provided with a peripheral groove E2 to receive a drag-spring F having a radially )rejecting end F extendinginto the slot D3 ofthe sleeve or tumbler D. E3 is a segmental lug projecting from the enlarged head E of the tumbler E adapted to cooperate with a pin G3 projecting through the enlarged head'G of the tumbler G. E* is a slot in the tumbler 'E adapted to re- `ceive the tongue C of the bolt C when brought into proper registration with the `groove D of the sleeve or tumbler D and with the slofJ G2 in the tumbler G. F, is another drag-springlodged in the groove of the enlarged'head ot the tumbler G, its radially projecting` end F also extending into the slot D3 of the sleeve or tumbler D. H, isla driving disc sleeved upon the' bolt C and provided with a lug or key H projecting into a key-way C2 in thebolt that the disc may be rotated when the latter is turned. H2 is a segmental lug projecting from the driving discadapted to engage the Lipper end of the pin G3 projecting above the tumbler G, whereby the latter may be rotated to bring the slot G2 of the tumbler G and the slot E4 of the tumbler E into registration with the slot D of the sleeve or tumbler 'D upon a manual predetermined rotation ot the cap'B, obtained through the (3o-ordinationr of the graduations on the cap and lock casing. N, denotes a nut screwed into the tapped upper end of the lock casing A. counterbored on its under face to receive the' driving disc H. its surrounding outer edge bearing upon the edge ofthe sleeve or tumbler D" to secure the latter against dislodgrnent or'A displacement. N is a pin extending through the wall ofk the lock casing into the nut to securel the latter when in position;

lnorder that the cap B' may be readily rotated upon the end ofthe lock casing it may be fitted with a slidable crank arm l. {itted with a knob l, the'arm being slotted as at I2 tor the passage of a pin B2, whereby it is secured to the end4 ot the cap;-and when noteinployed for rotatingr the cap itmay be pushed out ofthe wayv and in alignment with the end of the cap. J. is a washer sleeved upon the end of the bolt having-a lured extending into the key-way C2 of the bolt that it may be rotated thereby. J2 is a raised portion struck from the body ot the metal adapted to enter any of the series of serrations A3 formed in the end ot the lock casing.` Thel serrations A3- co-ordinate with the graduations B and A on the lock casing and cap. The serratons are separated at one point by a blank-portion A4, as indicated in Figure l1 td provide a starting point for adjusting th-e tumblers. K, is a spring sleeved upon the end of theJ bolt D adapted tobearnpon the washer .l and `movable plunger havinga projecting stem M riveted tothe end link at the opposite end of the chain. The plunger M is 4provided at its tree end with a peripheral groove M2 tov receive the end of the bolt C when the latter is in locked position as shown in'Figur'e 2.

f Having now indicated the several parts by reference lettersthe construction and operation of the device will be readily understood. I

While the embodiment' o-t the device shown in the drawings is especially adapted for se.- curing a spare tire to a' supporting frame it will be apparent that it may' be employed as an ordinary doorlock or as a lock for other purposes for which it may be adapted.

ln describing its operation it will irst be assumed that the bolt is in its unlocked position as indicated in Figure la, the removable plunger M carried by the free end of the chain is then inserted as indicated gthe cap to which the bolt C is attached is then forcedk inwardly against the action of the spring K, thereby causing the forward end of the bolt to enter the peripheral groove M2.- at the end of the removable plunger. The cap is then manually rotated to shift the relative positions of the tumblers E and G so'that the grooves E4 and G2 of the respective tumblers are out of registration with the groove D in the sleeve D, thus securing the tongue C of the ybolt C against return and in locked position as indicated in Figure 2. Vhen it is desired to unlock the device the tumblers are rotated through the manual operation of the cap B so as to bring the grooves E4 and G2 of the respective t-uniblers into registration with the groove DA ot'the sleeve or tumbler D that the tongue C ot the bolt C maybe vforced out of the peripheral groove M2 bythe spring K into the `groove D', F# and G2 ot the respective tumblers, this resultV being` effected as will be understood, through the arbitrary adjustment oft the graduated cap with reference to lthe indicating arrow or graduation A on the wall of the lock-casing. `Upon the tumblers being brought into proper registration the spring K forces thek cap B outwardly ((see Figure la), carrying therewith the bolt ,-the tongue C ot the bolt entering the aligned grooves D. E4 and G2 of the respective tumblers-` thereby releasing the plunger M, that it may be removed from the casing.

The adjustment ofthe tumblers may be effected at night or inthe dark by counting the audible click resulting from the raised port-ion Jot' the washer entering the diterent serrations as the cap is rotated ;-the starting position being, determined bythe spaced portion A4 between the serrations, as will be readily understood.

`Whilel have shown an adjustablecrank arm I attached to the rotatable cap .for the convenient .operation ofthelatter1 the arm' may be dispensed with and the outer wall of the cap may be milled to provide a good gripping surface to assistin its manual operation.
